Wireless communication systems offer a flexible, cost-efficient alternative to wired applications. In the industrial environment, they are used especially for the networking of movable or spatially separated system components as well as mobile systems. With today’s automation solutions, however, it is necessary to take into account numerous factors and challenges, such as adjacent wireless communication systems, changing propagation conditions or faulty configurations. To address these issues, innovative algorithms and procedures pave the way for targeted condition and fault analysis in industrial wireless networks. These supply information on factors such as connection quality, stability, transmission reserves and existing transmission problems in your networks.

Wireless communication in the production environment also plays an increasingly important role in the case of real-time requirements. For example, systems must frequently be connected to higher level control systems with very short cycle times in the single-digit millisecond range. To avoid the disadvantages of wired solutions, such as restricted flexibility, Fraunhofer IIS/EAS is developing a new kind of wireless technology that enables real-time signal transmission with extremely low latencies and maximum reliability.
